NetApp DataMotion for Volumes enables you to nondisruptively move a volume from one aggregate to another within the same controller for capacity utilization, improved performance, and to satisfy service-level agreements. In a SAN environment, FlexVol volumes and the LUNs in the volumes are moved nondisruptively from one aggregate to another.
In a volume move, SCSI applications accessing different LUNs in the volume can continue to run during the move. Applications that use FC and iSCSI to access a LUN in the volume that is being moved do not see any I/O disruptions during the volume move. You can continue to access data in the volume during and after the volume move.
The volume move occurs in three phases: setup phase, data copy phase, and cutover phase.
